kotlin使用lamda进行回调

// 定义一个成功的变量
    private lateinit var success: (resave: Boolean, message: String) -> Unit
    // 定义一个失败的变量
    private lateinit var failed: (resave: Boolean, message: String) -> Unit

    // 给函数复制
    fun onSuccess(listener: (resave: Boolean, message: String) -> Unit): FilterSaveNetHelper {
        this.success = listener
        return this
    }

    fun onFailed(listener: (resave: Boolean, message: String) -> Unit): FilterSaveNetHelper {
        this.failed = listener
        return this
    }
